When I had my iPad 3rd Gen, I had a Deviceware back cover and the Apple Smart front cover. The Deviceware back cover had a single metal strip for the front cover to "latch" onto. I loved it and was thinking about doing the same thing to my Apple Smart Case on my Air. I was going to see if the front cover of the Smart Case is strong enough to stick to a plain piece of metal or if a weak magnet was needed. It already kinda sticks to the back of the case, but it's not strong enough to stay there.
